Background
Introduced in 1996 as Jaguar’s answer to the ageing XJS, the XK8’s graceful and restrained lines were penned by chief stylist Geoff Lawson, and were available as either a three-door hatchback coupé, or as a two-door convertible with both models being presented in a 2+2 format.
Under the clamshell bonnet sat a 4.0-litre, 32-valve V8 engine, codenamed the AJ-V8. This was all mightily impressive as it sat, but for real performance enthusiasts, the XK8 never quite hit the mark.
Thankfully, their prayers were answered in 1998, when the ‘big brother’ XKR was introduced. Now, performance Jaguar enthusiasts had something to get excited about. The same 4.0-litre AJ-V8 engine was used up front, but a 2.0-litre Eaton supercharger was bolted on, bolstering the power output to an impressive 370bhp, all of which was sent through the sizeable rear wheels. The XKR had a top speed of 155mph and can shift from 0 to 60mph in 5.2 seconds.
Whilst the power output was a marked change, visual differences between the ‘8’ and the ‘R’ were minimal, being limited to a mesh grille, rear spoiler and a louvred bonnet to improve airflow.
Interestingly, the XKR also received a Mercedes-derived W5A580 transmission, which was upgraded to a ZF six-speed item in 2002, when the XKR and XK8 were face-lifted, and displacement was increased to 4.2 litres.
What some thought lacking with the XKR though, was the feedback coming through to the driver in the run up to a loss of adhesion or control. A small tuning company called Paramount Performance stepped forward and declared that they could give the XKR the handling and sporting performance it deserved.
